is a specification, like reference characters 'on' the drawingsindicating like parts in the several figures.

This invention relates to machines for' operating .upon the breastportions of shoe heels-and particularly to machines for forming thebreast portions of Louis heels after they are attached to their shoes.

soineshoeheels, for example, Louis heels, have their breast facescurvedlongitudinally of the shoe and are usually breasted by relativelymoving the heels and thebreasting means transversely of the heels. Whena'heel is breasted by relative traversing movement of the heel andcutter orcutters transversely of the heel it is difficult to form a goodedge on the side of the heel where the cut is finished. It has beenproposed to employ two cutters which cut from opposite sides of the heeland meet at the center of the breast. This method has been foundimpracticable because a fin or blemish will be formed at the center ofthe'breast. One object of this invention is to provide a machineemploying cutters acting inwardly from opposite sides of the heel soorgan ized and operated that not only will both side edges of the heelbreast be properly formed, but also so that no tin or blemish will bemade on the breast face.

Heels of the Louis type have a portion ad wardly of the shoe along theshank. The breast face of this portion should be formed, at its frontedge, flushwith the shoe shank and should be transversely curved tocorrespond with the transverse curve of the shank and to merge into theportion of the breast which extends heightwise of the heel. A furtherobject of this invention is to provide a machine having a contouredcutting blade so movable transversely of the heel as to cause theportion of the knife which acent to the heel-seat which extends for cutsthe baseportion of theheel breast to follow the transverse curve ofthesha'nk.

The portion of a heelbreast adjacent to the" top lift is frequentlyfbrmed with a curvature differing from that of the main" p Thiscurvature isg generally concave relatively to'the heel and oi-nun of thebreast.

is known as a scallop and is best formed by a rotary cutter having'a'predetermined movement relatively to'the hee'lof the shoe. A furtherobject of this invention is to'pro vide a machine havingsuch a cutterand preferably with means for causing the cut.- te'r automatically toscallop the heel;

Other cbjeets'of the invention are to proe vide an improved machine forthis w 'ork' which will be lnorea'ccurate, effective, and

expeditious, and which will require less at-- ten'tion from an operatorthan prior ma.- chines.

A feature of the invention consists in an organization including workholding means and a pair of opposed cutters to=- gether with means forrelatively moving the work and one cutter to initiate the'cut' tingoperation at one side of the work, and" means for relatively moving thework and the other cutter to complete'the cutting operation. Preferably,the cutting operation of the first cutter ceases prior to the completionof the action of the second cutter. shown herein, the cutters begintoact at opposite sides of a" face of the work and the surface formed byone cutter extends to and preferably partly across the surface formed bythe other cutter without any line Another feature of the inventionconsists in an organizationin which a knife is moved 1 a i I 1 I in acurved or arcuate path transversely of Q j r 1,512,884

the shoe to treat the shoe bottom, for instance, to form a convexsurface on a heel breast. In order convexly to curve a portion of theshoe bottom extending lengthwise of the shoe, for example thebaseportion of a Louis heel, the knife may be moved about an axisextending longitudinally of the shoe and preferably locatedsubstantially at the center of the curve of the shank so that theportion of the knife adjacent to the shank of the shoe will begin to cutsubstantially in the plane of the surface of the shank at its edge andwill follow the curve of the shank as it advances toward the'center ofthe heel breast, thereby cutting the front edge of the base portion ofthe heel flush with the surface of the shank and giving the remainder ofthe base portiona .convexly curved surface corresponding to the curve ofthe shank. Preferably two knives are organized to act as described andare moved about a common axis. As shown, the knives may be contoured toform on the base portion of the heel a surface curved longitudinally ofthe heel and extending forwardly along the shank, the forward edge ofthe said portion being flush with the shank surface and following thetransverse curve of the shank by reason of themovement of the knifeabout the said arms.

A further feature of the invention con sists in an organization forrelatively moving the knives and the heel bodily in the direction of thelength of the heel and for operating the knives a second time in thecycle of the machine to cause the knives to make a second or finishingcut by which a thin chip is removed from the heel by a movement of theknives which is parallel to the first, movement. As shown, the knivesare moved bodily rearwardly of the heel between successive operations ofthe knives. 7

Another feature of the invention consists in an organization comprisingmeans for holding the shoe in a fixed position, means forv breasting theheel, and a rotary cutter forgiving a portion of the breast face a shapedifleremt from that formed by the breasting means. As shown herein, thero tary cutter forms a'concavity or scallop on the portion of the breastface adjacent to the top lift of the heel. Preferably the rotary cutteris arranged for movement substantially lengthwise of the heel about anaxis above the cutter and over the rear part of the shoe so that thecutter may be swung into operative relation to the heel breast, the pathof swinging movement being such as to include a slight component ofmovement heightwise of the heel toward the shoe so as to cause thecutter tomove into position opposite to the portion of the heel breastwhich is adjacent to the toplift before it is moved further lengthwiseof the heel to perform its cutting operation. The cutter is preferablyfrusto-conical in shape and arranged with its shorter diameter at thegreater distance from the shoe. In the organization shown, the cutter iscontinuously rotated and is swung in timed relation to the action of thebreasting means to move it from a position where it is out of the pathof the shoe when inserted'into the'machine into operative relation tothe heel and then back to its initial position where it is out of theway of the shoe during the removal of the shoe, the movements ofthe-cutter being effected automatically.

Since the knives and the rotary cutter are moved in predetermined pathsto. do their work, it is important that the shoe be held in the machinein a predetermined position.

Accordingly, a still further feature of the.

treadle may conveniently be utilized to set the machine in operation.

Another feature of the invention consists in an organization including astop or abut ment and means for clamping the shoe against the stopcomprising means engaging and supporting the cone of the, last which isdepressible by pressure on the shoe to allow lasts of various heights tobe readily positioned in the machine, with means for looking thesupporting means from depression and applying thereto a predeterminedmove ment toward the stop to ensure that a last of any height will befirmly seated against the stop before the shoe is operated upon. Thelocking of the shoe support and the predetermined clamping movement are,as shown herein, effected by power operation of the machine. lreferablytwo stops are provided as above explained. V

Other features of the invention consist in improved means for locatingthe heel and toe of the shoe and in other details of construction andcombinations of parts which, as well as the features above mentioned,will appear more fully from the, following detailed description whenread in connection with the accompanying drawing and will be pointed outin the appended claims.

tqflimitits'swinging movement the member 22Isprovided'with-liigs 30, 32which are arrahge'd' to engage respectively the upper and lower faces ofa lever arm 34' to which the member 22 is-p-iv'otedat 28; A shoe isplaced upon thepin 10 of'the ack with the ack inoutwardlyswun'g'position and is then movedlongitiidiiially toward the machine.the heel passing between stop arms 40,42 which at that timeareseparatedtopermit passage of the heel between them. During thismovement the post 16 is depressed somewhat agaiii'st the spring24to'permit the 't'readf'ace of" the heel to pass beneath a tread plate46 Iii-demeanor adjustment longitudinally of 4 i"s' p'laiivlew, partlyins-ection, of" the: means for mounting and operating the the-shoe uponthe forward end of a: lever 48 pivoted to the machine frame at" 50. Theplate 46- has a flange 52' which engages the rear end of the heel andlimits rearward movement there-of. Passing through the lever 48 is a rod54 having below the lever a collar 56 which limits downward movement ofthe lever and abovethe lever having a spring 58 which normally holds thelever 48 against the collar 56. After the shoe has been positiohedbeneath the tread plate 46' it is released by the operator and raised bythe spring 24' into contact with the plate 46, the spring 58 beingsomewhat stiffer than the spring 24 so as to maintain the spring 24under tension and the lever 48 against the collar 56. The adjustment ofthe collar is such that the plane of the shoe shank will be below'theplane of inwardly swinging movement of the stop arms 40', 42. These armsare pivoted at 60, 62, respectively, to the tr'ansverseportion 64 of aU-shaped member, the arms 66,68 of which arepivoted at '70 to themachine frame. The arms 66, 68 are slotted as at 72 (Fig. 1) andcap'screws 73 pass'through the slots and are'threaded into the machineframe. By loosening the screws 7 3 the U-shaped member may be swungabout the pivot 7 O and hence the stop members 40, 42 adjustedvertically for apurpose which will appear hereinafter; Above theirpivots 60,62 the stop members 40, 42 are provided with extensions 80, 82(Fig. 2) which are acted upon by a wedge member 84 mounted in guides inthe frame and operated by a lever 86 pivoted at 88 to the frame andconnected at itsrear end toa rod 90, the lower end of which is guided inthe frame and rests upon a lever 92 which is pivoted to the frame at 94and its forward end formed as the treadle 8. The lever 92'eXtendsrearwardly beyond the rod 90 and has connections to the clutch so thatdepression of the treadle 8 will first raise the rod 90and thereaftertrip'the clutch. Raising of the rod 90 causes depression of the wedgemember 84 which causes the stop members 40, 42 to approach each otherand assume positions over the shank of the shoe. The wedge member 84 hasparallel edge faces which engage the projections 80, 82 after the wedgepo-rtionhaseff'ected the desired movement of the stop members 40, 42andhe'ii'ce' movement of the wedge member 84 may be continued by furtherdepression of the treadle to trip the clutch. The position of the shoeshank as determined by the tread plate 46 will, of course, vary withhe'e'ls'of different heights and, therefore, the collar 56 should be soadjusted that the shank of the shoe being operated upon will be locatedin at plane somewhat below the plane of swinging movement of the stopmembers 40, 42.

After theshoe has been positioned as described", the treadle will bepartially clepresse'd to move the stop nembers lO, 42 over the shoeshank and thereafter further depressed to start the machine. In thedrawings, the machine is shown as having startedand the shaft 4 ashaving moved through about 30 of its rotation. In order to hold the shoefirmly in predetermined position, it is important to press the shoefirmly against the stop members 40, 42. In the constraction shown thisis effected by first looking the post 16 against depression and thenlifting the member 22 to force the shoe against the stop members. Thepost 16 is provided on its rear face with teeth (Fig. 2 which areengaged by pawl block 102 which is urged into locking engagement withthe teeth 100 by a leaf spring 104 and is mounted on an arm 106 of arock shaft 108 mounted in a rearward projection of the sleeve member 22.Another arm 110 of the rock shaft 108 is connected by a link 11.2 to theforward end of a lever 114 pivoted to the lever 34 at 116 and connectedbetween its ends to the machine frame by a link 118. The lever 34 ispivoted to the machine frame at 120 and its rearwardly extending arm 35is pivoted at 121 to a rod 122 connected at its lower end to an arm 124of a bell crank lever fulcrumed on a shaft 126, the other arm 128 of thebell crank carrying a roll 130 which engages an edge earn. 132 mountedon the shaft 4. Before the machine starts the pawl block 102 is out ofengagement with the teeth 100, and when the machine starts the cam 132moves the arm 128 to the right (Fig. 2) effecting a downward pull on therod 122 and causing the outer end of the lever 34 to be raised, carryingwith it the sleeve member 22. Since the outer end of the arm 110 is heldby the connections 112, 114, 118 from substantial movement with thesleeve member 22, the pawl block 102 is caused to engage the teeth 100,further predetermined movement of the lever 34 causing the shoe to bepositively raised and forcibly clamped against the stop members 40, 42.The tread plate 46 is raised, of course, by the shoe and the spring 58somewhat compressed. In order, however, firmly to hold the heel it isdesirable to increase the tension of the spring 58 when the shoe isjacked and this is accomplished by connecting the rod 54 to the leverarm 35 at 121 so that as the arm 35 is depressed as described the rod 54will be pulled down and increased tension applied to the spring 58.

It will be observed that by the mechanism described shoes having lastsof different heights are positioned and raised upwardly withsubstantially the same predetermined pressure against the stops 40, 42.The last and shoe are first measured by insertion between the treadplate 46 and the yielding jack post 16. Then the jack post is locked bythe pawl 102 in the position it has been made to assume by the height ofthe particto permit the passage of the rod 142 through it and to permitmovement of the wedge member as described. 7

The shoe is now positioned and held for the operation of the breastingknives 150, 152 which are located one on each side of the heel and aremoved transversely of the heel breast toward the center of the heel. As

shown in Fig. 2, th knives 150, 152 are segment-shaped or, strictly, areshaped as sectors of an annulus, and are mounted to oscillate about anaxis 154 which extends longitudinally of the shoe and is locatedsubstantially at the center oftransversecurvature 0fthe shoe shank.Preferably the knives are contoured as shown in Fig. 4 so that theportions of the knives adjacent to the base of the heel will form uponthe .heel a forwardly projecting portion which is convex relatively tothe shank, the front edge portion of which is trimmed flush with thesurface of the shank. The knife is clamped to an am 156 as shown in Fig.4. One edge of the knife rests against a flange 158 and the other edgeof the kniferis engaged by a.

clamping piece 160 which has a bearing at 162 in the arm 156 and isforced against the knife edge by a screw 164. The arm 156 is mounted onthe bearing shaft 154 and extends to the left hand side of the machinewhere it is connected by a bolt 166 to a rod 168 which is connected atits lower end to a lever 170 2) fulcrumed on the shaft 126 and havingthereon cam roll. 172 which engages a suitable cam path formed in a camblock 174 affixed to the shaft 4 (Fig.

1.) The knife 152 is mounted on an arm 176 by means similar to thatdescribed for clamping the knife 150,and the arm '17 6 has a sleeve 178which surrounds the shaft 154 and hence permits movement of the knife152 about the same axis as the knife 150. The arm 17 6 extends to theright hand side of the machine where it is connected by a bolt 180 to arod 182-which is connected at its lower end to a lever 184 fulcrumed ona. shaft 186 and having between its ends a cam roll 188 which engages asuitable cam path formed in the front face of the cam block 132.

Thearm 156 is shaped, as shown in Fig. 2, to pass beneath the arm 176and avoid interference therewith when the rods 168, 182 are drawndownwardly by their respective cams to cause the knives to be oscillatedaboutthe axis 154 and their edges advanced a thick or roughing chip, andthen by the removal of a thin or finishing chip. In the constructionherein shown the first or roughing chip is cut as described but theaction of the knives is arrested before they meet at the center of theheel and the knives are then withdrawn, the roughing chip remainingattached to the heel breast. The

knives are then moved bodily rearwardly of the heel a short distance andare again operated toward the center of the heel. The

bodily rearward movement of the knives is effected by the followingmechanism: Outside of the sleeve 178 is another sleeve 190 and both theshaft 154 and the sleeve 178 are held from longitudinal movement in thesleeve 190 by a washer 192 secured by a nut 194, as shown in Fig. 4. Thesleeve 190 is provided with a slot 1796 (Figs. 1 and 1) which isinclined to the direction of the axis 154 and which is engaged by ascrew stud 198 threaded through the machine frame and having afrusto-conical end which enters the slot 196. The sleeve 190 is providedwith an arm 200 connected by a bolt 202 to a rod 204, the lowerend ofwhich is pivoted at 205 to a lever 206 fulcrumed on the shaft 186 andhaving between its ends a cam roll which engages a cam path in the rearface of a cam block 208. After the knives are operated partially toremove the roughing chip and withdrawn the cam 208' acts through the rod204 to pull down on the arm 200, thereby rocking the sleeve 190 andcausing it, by reason of the engagement of the fixed stud 198 with theslot 196, to be moved rearwardly, carrying with it the bearings 154, 178of both the knives. This rearward movement, of course, is very slight, amovement of one thirty-second of an inch being usually suflicient. Theknives are .again operated to approach the center of the heel and toremovea finishing chip from the portion already roughly breasted. It is,.of course, impracticable to move the knives until they meet in thecenter of the heel, one reason being that if the knives are adjusted sothat they will practically meet when no shoe is being breasted theywould fail to meet when under the stress of performing the breastingoperation by reasonnf springing of the parts, and as a result a fin orrough place would be formed at the center of the heel breast. To avoidthis difficulty among others, in the construction shown the knives, upontheir second cut, are made to approach each other as on the first cut,and then the action of one knife is arrested and the knife preferablywithdrawn while the action of the other knife continues slightly pastthe center of the heel nd fie t a mu a a d clean ve nce of that chip aswell as of the first chip clings to it. action of the knives iseffected, f s me y sui ably shaping t c m p hs wh ch opera th kniv s wll be readily understood.

After'the breast face of theheel has been formed in the mannerdescribed, it is usually desirable to 01111 3 concaved portion on thebreast face of the heel adjacent to the top lift, usually referred .toas a scallop. In the machine herein shown this operation is effectedautomatically by the following mechanism: rotary cutter 210 is mountedon a shaft; 212 on the opposite .end of which is apulley1214 which iscontinuously driven a belt 216 extending over'idler' pulleys 218 to apulley 219 on a counter shaft 220.

A pulley 222 on the counter shaft and fast with the pulley 219 is beltedto a portion 224 of the: driving pulley 6. The shaft 212 of the rotarycutter is mounted in a carrier 226 which is pivoted to the machine frameat 228 on an axisextending transversely of the shoe and has a rearwardlyextending arm 23OQto-whi'ch is connected at- 232 a rod 234. The lowerend of the rod 234 is connected at 236 to a lever 238 fu-lcrumed on theshaft 126 and having thereon a cam roll 240 (Fig. 1) which engages aredge cam formed on the cam block 208. After the breasting of the heelhas been efiected as described, the roll 240 is actuated to pushupwardly on the rod 284 lifting the arm 230 and causing the crittershaft to move about the axis 228 and the cutter to approach the breastface of the heel and perform thereon the scalloping operation. Since thecutter shaft 212 is inclined to the direction of the height of the heel,and its carrier moves about the axis 228-which is located rearwardly ofthe heel, the cutter not only moveslengthwise of the heel into operativerelation to the heel, but has a component of movement heightwise of theheel so that it descends from a location above theplane of the topliftto a position slightly below that plane prior to the continuedlengthwise movement which causes, it to engage and scallop the heel.Preferably the cutter 210 is provided with a shield 242 which extendsaround all portions of the cutter except the portion which'acts upon theheel. It will be noted that the stop members 40, 42 are shaped toaccommodate between them the rotary cutter audits shield.
